You guys also think this one is science and this one.
voice-verified
is also science.

Thank you, Cara.

So polymers generally are made from fibers which are woven together.
voice-verified
And those are very permeable because there's gaps in between the weaving.
voice-verified
So this polymer, however, was made as a two-dimensional material.
voice-verified
So it's a single film.
voice-verified
And therefore, there's a solid crystalline structure with no gaps.
voice-verified
And so that's why it doesn't let the gas escape.

through.

No gases?

No gases.

So they tested it with helium, nitrogen, oxygen, argon, helium, methane, and sulfur hexafluoride.
voice-verified
Do you guys remember huffing sulfur hexafluoride?
voice-verified
The opposite of helium.
